United States Patent F a 2,794,606 BUTT-END ROLL REWINDER flames Lambert Miller, Washington, Mo. Application November 8, 1954, Serial No. 467,417 3 Claims. Cl. 242-58) This invention relates to a butt-end roll rewinder, and

comprises an attachment for a flat bed newspaper press of the Goss or Duplex type whereby the newsprint paper on butt-end rolls may be salvaged, and paper waste may be avoided. Such butt-end rolls result from changes on the press. For example, after an 8-page run, wherein a 70-inch roll is used, some unused paper is left on the roll. If new a 6-page paper is to be printed, it is necessary to use a 56-inch roll. Since the 70-inch butt-end roll is not sufiicient for a run on another 8-page paper, it is waste, as the time and labor required to set up the roll and thread the press is often more than the value of the paper remnant on the butt-end roll.

' With the device of my invention, this waste may be eliminated. When a 70-inch roll is again to be used, the 70-inch butt-end roll may be spliced thereto and rewound thereon. In another phase of the invention, several buttend rolls of the same length may be combined to form, a supply sufiicient for a run of the press.

An object of this invention is to' salvage butt-end rolls remaining after a run of a flat bed newspaper press.

Another object is to provide an attachment to he'used with flat bed presses whereby paper from butt-end rolls may be rewound onto a paper supply in the press.

An additional object of the invention is to provide an attachment for flat bed presses whereby the supply roll of the press is converted into a rewind roll for salvaging butt-end rolls.

These and other objects will be apparent from a consideration of the following specification taken in connection with the accompanying drawings forming a part thereof, and in which like reference characters indicate like parts throughout.

In the drawings:

Figure l is a perspective view showing the supply end of a flat bed press with my rewinder operatively associated therewith;

Figure 2 is a vertical section through a portion of a butt-end roll and one of its supporting stanchions; and

Figure 3 is a detail on line 3-3 of Figure 2, looking in the direction of the arrows.

Referring now to the drawings in detail, numeral 10 denotes a portion of the framework of a flat bed printing press of well-known type and forming no part of my present invention. This framework 10 supports the usual rollers 11, 12, and 13 over which the paper is fed into the press in known manner. Roll 12 is mounted on swinging bracket 14 (a like bracket being provided at the other end thereof) whereby the amount of wrap of paper about roll 11 may be adjusted. For this purpose, bracket 14 is pivoted on shaft 15 and is adjusted by screw 16 mounted in boss 17 and 18 and turning in nut 19 pivoted on bracket 14. Since these are known parts of the press, no further description or details thereof is deemed necessary.

Paper P is threaded over the rolls above mentioned in ice the usual manner and passes between the bed and platten mechanism of the press.

Extending rearwardly from frame member 10 is a bracket 20 having a notch therein for supporting the mandrel 22 of a roll 23 of'paper for supplying the press.

Paper from roll 23 would, in normal operation of the press, be spliced to paper P on the press. The paper P, as shown, has previously been severed from a roll on stand 20. However, it is shown in position for the practice of my invention.

At a suitable distance from the paper roll stand 20 are a pair of standards or stanchions 24 and 25 adapted to hold a butt-end roll. Standards 24 and 25 are suitably supported on the press room floor by means of bases 26 and 27. Each standard is provided with a hearing as shown at 29 in Figure 2 to accommodate the mandrel 30. Standard 25 is formed in two sections 31 with a righthand thread,'and section 32 with a left-hand thread, the sections being threaded into a suitable coupling nut 33. When not in use, the attachment is readily removed from the rear of the press to suitable storage.

In order to insure parallelism of mandrels 22 and 30, a pair of identical'alignment bars 34 are provided. Each bar has a head 35 at either end, provided with a slot 36 which is adaptedto embrace mandrel22 or mandrel 30 as the case may be. The distance between the center lines of the slots 36 of each bar is the same. If the mandrel of any roll is too short for the space between standards 24 and 25, a section 30 may be attached by means of coupling 37.

The butt-end roll is indicated by numeral 38 and is mounted on mandrel 30 by means of the usual cone centering blocks 39. i

A brake pulley 40 is adapted to be mounted on mandrel'30 by means of set screw 41. A brake lever 43 is pivoted at 44- on standard 24 and is provided with a shoe 45 adapted to engage pulley 40. A bracket 46 mounted on or integral with standard 24 extends parallel to the end of lever 42. A screw 47 in this bracket is arranged to engage lever 42 and press the shoe 45 against drum 40 with pressure suflicient to impose desired tension on the paper being drawn from roll 38. This pressure may be diminished from time to time as the roll 38 becomes smaller.

A pulley 48 is adapted to be secured to mandrel 22 by means of set screw 49, to drive roll 23. The driving mechanism comprises a motor 50 mounted on base 26 and having a pulley 51. A pair of standards 52 and 53 mounted on base 26 each carries a pillow block 54 in which blocks there is mounted a shaft 55. On shaft 55 are mounted two pulleys 56 and 57. Belt 58 connects pulley 57 with motor pulley 51, and belt 59 connects pulley 56 with pulley 48. Pulleys 56, 57 and belts 58, 59 comprise a reducing gear for driving roll 23 at reduced speed by means of motor 50.

In order to regulate the belt tension on belt 59, a lever 60 is pivoted intermediate its ends on stand 52 by means of pivot pin 61. A plate 62 having notches or dents 63 for engagement with one end of lever 60 is provided. The opposite end of lever 60 carries a pulley 64 adapted to bear against belt 59. This arrangement constitutes a belt tightener to regulate the tension on belt 59, and to permit slip in the drive as the diameter of roll 23 increases.

The operation of my attachment will now be described. The butt-end roll 38 is placed on standards 24, 25 and alignment bars 34 are positioned over mandrels 22 and 30. Paper from roll 38 is spliced to the paper on roll 23. Assuming that pulleys 40 and 48 have been installed and brake shoe 45 has been given preliminary adjustment, motor 50 is started. As roll 23 rotates, the paper is re- Patented June 4, 1957 woundifrom roll 3 8 Bralge shoe 45 may be further ad usted to produce the desired winding of the paper.
